The price of flights rises as the flights get more full. I faced the same conundrum on my last trip.

It works out much cheaper to book online as soon as possible, to avoid any hikes in the fares.

It isn't possible to make such generalisations. The price from day to day might change for all sorts of reasons and will go both up and down over any given period.

If you see a price you're happy with, book it. If not, wait and see if that price comes up in the future.
